Yes, I've noticed that about the jetpack levels. And that's what I love about this game: great combination of arcade style agility and puzzle solving. But on level 11 of Fly Like Condor, it is not a matter of steady hands. There is a mechanical door in the upper left corner of the room where the professor starts. And it *always* closes before I can fly to it. There's a switch in the bottom right corner, but no matter how many times I flip the switch, I can never even come close to making it to the door in time. It seems like a glitch. Has anybody else noticed this? Is there a trick that I'm missing?
